Featuring Luna Moth today
Handy highlights for quick reference, conversation, or the start of a lesson.
Luna moths do not have mouths or digestive systems! As adults, they cannot eat and live for only about one week, using all their energy to find a mate and lay eggs.
Their long, elegant wing tails are not just for looks; when they spin in flight, they confuse the echolocation (sonar) of bats, causing the bats to miss when they try to catch them!
The name 'Luna' comes from the Roman goddess of the moon, because these moths are nocturnal and fly only at night.
Before becoming a moth, the green caterpillar spins a papery silk cocoon on the forest floor, wrapping it inside a fallen leaf to hide from predators.
Male Luna moths have large, feathery antennae that are extremely sensitive, allowing them to smell a female's scent from over a mile away!
They have large spots on their wings that look like eyes, which can startle predators into thinking the moth is a much larger animal.

Open data
Species pages state sizes the way a reader expects them — “46 pounds”, “3.5 feet”, “10 to 12 years”. Those are readable but not comparable, so each one is parsed into a single unit system. That makes the ranking on every species page a computed figure rather than a quoted one, and the whole table is published for anyone to check.
